The United States Senate election of 1922 in New Jersey was held on November 7, 1922. Incumbent Republican senator Joseph Frelinghuysen ran for re-election to a second term in office but was defeated by Democratic governor Jersey Edward I. Edwards.
Primary elections were held September 26. Frelinghuysen defeated a progressive challenger, George Record, in the Republican primary, while Edwards was unopposed for the Democratic nomination.
This was the second of four straight elections to this seat in which the incumbent was defeated.
Though Frelinghuysen was opposed in the primary by George Record, who had made several unsuccessful campaigns for office, Frelinghuysen was assured of strong political backing and considered a heavy favorite for renomination.
Record criticized Frelinghuysen's vote to acquit Truman Handy Newberry and declared that he was out to break up the "Millionaires' Club" in the Senate. He was informally endorsed by many union officials, whom he had counseled as a private attorney.
Frelinghuysen defeated Record by a two-to-one margin.
The first candidate to announce for the Democratic nomination was state senator Alexander Simpson. On April 14, Governor Edward Edwards announced his candidacy as a "wet," or anti-Prohibitionist candidate. Simpson, who claimed he had not entered the race until Edwards had pledged not to run, withdrew.
Edwards was ultimately unopposed for the nomination.
